Answer:
There are six of them, based on the common compound that they are synthesized
Explanation:
The family of L- glutamate come from the cetoglutarate compound from the Kreps cycle. The family of L-serine, come from 3 - phosphoglicerate compound from the glucolisis. The L - aspartate family, that come from oxaloacetate compound, from the Krebs cylce. The piruvate family that come from the piruvate, from the glucolisis. The aromatic aminoacids, that come from eritrose - 4 - phosphate, from the pentose cycle. And the L histidine family, that come from the ATP.
 
        
             
        
        
        
The correct answer is:  5) NER recognizes helix distortions, while BER recognizes specific base damage.
DNA damage that occurs as a result of radiation, oxidizing reagents, chemicals and other mutagens can be repaired. Excision repair repairs single strand DNA damage and it includes:
•	Nucleotide excision repair (NER)-it detects and repairs types of damage that distort the DNA double helix such as those of UV radiation (thymine dimers); not only the damaged nucleotide(s) are removed but also a surrounding patch of DNA
•	Base excision repair (BER)-it detects and removes certain types of damaged bases (small, non-helix-distorting bases); enzyme glycosylase is responsible for this type of repair
